Question

what does the abbreviation cad mean?
congestive aorta disease
congestive artery disease
coronary artery disease
coronary aorta disease

Explanation:

CAD stands for coronary artery disease. Coronary arteries supply blood to the heart. When these arteries get blocked or narrowed due to plaque buildup (atherosclerosis), it leads to coronary artery disease. Congestive is not part of the standard abbreviation meaning. Aorta is a different major blood vessel (the main artery from the heart, not the coronary arteries which branch off the aorta near the heart).

Answer:

coronary artery disease
